Welcome to Simple Dietz Performance Screen
We have improved Simple Fund 360 Investment Reporting for Planners and Investment advisers by adding a new Simple Dietz Method to the Investment Dashboard. The new method provides a more weighted measure when calculating the return on a portfolio than a simple return method.
The Simple Dietz method measures investment performance during a period, incorporating cash inflows and outflows.
The Simple Dietz method is named after Peter O. Dietz, author of 'Pension Funds: Measuring Investment Performance'.

Definition Table
| Notation | Definition | Notes |
| The beginning of the period | If there are no holdings at the beginning of the start date selected, t1 will be the date of the first purchase. | |
| The end of the period | If there are no holdings at the end of the end date selected, t2 will be the date of the last disposal. | |
| Opening Market Value | The market value of the asset(s) as at the beginning of the selected period. | |
| Closing Market Value | The market value of the asset(s) as at the end of the selected period. | |
| Net cash flow on a specific day i | Include any purchases, disposals, instalments, returns of capital and dividend/distribution reinvestments.
| |
| Income on a specific day i | The income amount is the amount of cash flow from the income received including any tax credits associated with the income.
It is assumed any income will reduce the market price of investment. |
Example Case:
Example 1: Non-Unitised investments/Bank Accounts
Formula used for Non-Unitised investments/Bank Accounts:
The time period selected is 01/07/2017 – 31/12/2017.
Example 1.1: Non-Unitised Asset 1 is purchased on the first day 01/07/2017 for 5000 and is not disposed of. No other purchases for this investment are made in this period. $100 of income is made on the investment.
| The beginning of the period | 01/07/2017 | |
| The end of the period | 31/12/2017 | |
| Opening Value | 0 (Note that Mt1 is the market value of all assets at the beginning of t1. The investment is purchased on t1 so Mt1 = 0) | |
| Net cash flow on the first day | 5000 | |
| Averaged net cash flow excluding the first day and last day | 0 | |
| Income for the full period | 100 |
Example 1.2: Non-Unitised Security 2 is purchased on 15/07/2017 for $1000 and is fully disposed on 15/08/2017. No other purchases for this investment are made in this period. $100 of income is made on the investment.
| The beginning of the period | 15/07/2017 (Note: If there is no holding and balance of a specific investment/bank at the start or end date of the selected period, Simple Fund 360 will calculate the rate of return of the period from the first purchase) | |
| The end of the period | 15/08/2017 (Note: If the investment is disposed of in the period, Simple Fund 360 will calculate the rate of return of the period until the last disposal date) | |
| Opening Value | 0 | |
| Net cash flow on the first day | 1000 | |
| Averaged net cash flow excluding the first day and last day | 0 | |
| Income for the full period | 100 |
| If the holding period of the investment is not the same as the selected period, users can hover over the investment to see which period Simple Fund 360 has applied to calculate the rate of return. |
Example 1.3: To calculate the return for the whole control account 72400, Simple fund 360 looks at all transactions within the control account during the selected period and treats them as one single investment. Therefore, on the control account level:
| The beginning of the period | 01/07/2017 | |
| The end of the period | 31/12/2017 | |
| Opening Value | 0 | |
| Net cash flow on the first day | 5000 | |
| Averaged net cash flow excluding the first day and last day | 1000 – 1000 = 0 | |
| Income for the full period | 100 + 100 = 200 |
Example 1.4: The opening balance for the bank account was -$2900. A purchase was made on 01/07/2017 for $5000. Other transactions to the bank account totalled $1199. Interest income for the bank account was $0.
| The beginning of the period | 01/07/2017 | |
| The end of the period | 31/12/2017 | |
| Opening Value | -2,900 | |
| Net cash flow on the first day | -5,000 | |
| Averaged net cash flow excluding the first day and last day | 0.5 * 1199 | |
| Income for the full period | 0 |
Example 2: Unitised Investments
Formula for Unitised investments:
The time period selected is 01/07/2017 – 31/12/2017
Example 2.1: NAB was purchased on 01/08/2017. 100 units were purchased at $2500. No other purchases for this investment are made in this period. $141.43 of total income is made on the investment (dividend + franking credit).
| The beginning of the period | 01/08/2017 | |
| The end of the period | 31/12/2017 | |
| Opening Value | 0 | |
| Closing Value | 2,957 (As there is no price available on 31/12/2017, the next nearest prices is used. $29.57 per share as at 29/12/2017) | |
| Net cash flow on the first day | 2,500 | |
| Net cash flow less Income for the full period* | 2500 - 141.43 | |
| Averaged net cash flow less income, excluding the first day and last day* | 0.5 * (0 - 141.43) | |
| Income | 141.43 (dividend + franking credit) |
*Note: As it is assumed any income will reduce the market price of investment, NCF is reduced by Income in these calculations.
If the latest security price of the investment is not the same as the end period date, users can hover over the closing value to see which price Simple Fund 360 has applied. |
Example 2.2: The fund held WBC shares coming into the selected time period. No other purchases for this investment are made in this period. No income is made on the investment. The investment is disposed of on 01/12/2017 where the proceeds of the disposal were $3400.
| The beginning of the period | 01/07/2017 | |
| The end of the period | 01/12/2017 | |
| Opening Value | 3,051 | |
| Closing Value | 0 | |
| Net cash flow on the first day | 0 | |
| Net cash flow less Income for the full period* | -3,400 | |
| Averaged net cash flow less income, excluding the first day and last day* | 0 | |
| Income | 0 |
*Note: As it is assumed any income will reduce the market price of investment, NCF is reduced by Income in these calculations.
Example 2.3: Rate of Return for control account 77600.
| The beginning of the period | 01/07/2017 | |
| The end of the period | 31/12/2017 | |
| Opening Value | 3,051 (market value of 100 units of WBC shares) | |
| Closing Value | 2,957 | |
| Net cash flow on the first day | 0 | |
| Net cash flow less Income for the full period* | -900 - 141.43 | |
| Averaged net cash flow less income, excluding the first day and last day* | 0.5 * (-900 - 141.43) | |
| Income | 141.43 |
*Note: As it is assumed any income will reduce the market price of investment, NCF is reduced by Income in these calculations.
Example 3: Portfolio Return
To calculate the Portfolio return, Simple Fund 360 uses the formulas used to determine each control account's return and sums up numerator and denominator of each formula.
Bank Account 60400 (Example 1.4):
| Numerator | 0 |
| Denominator | 2530.29 |
Fixed Interest Securities 72400 (Example 1.3):
| Numerator | 200 |
| Denominator | 5000 |
Shares in Listed Companies 77600 (Example 2.3):
| Numerator | 0 |
| Denominator | -7300.5 |

Reconciling the Simple Dietz Report figures
The Investment Performance Simple Dietz Report shows three figures for each investment
- Change in Value
- Income; and
- Income & Market Gain.
These are calculated differently to the figures shown on the Investment Dashboard and the Investment Income Comparison Report, which is why the income amount for an investment can look different across reports. The calculations below explain how to reconcile them.
Change in Value
This represents the movement in an investment’s market value over the period, after removing the effect of any purchases or sales made during the year (as these are cash flows in/out of the investment, not genuine gains or losses).
Change in Value = Closing Value − Purchases during the period + Sales during the period − Opening Value
Income
This is the total assessable income earned from the investment during the period, made up of:
Income = Franked income + Unfranked income + Interest/other income + Franking credits + Foreign income + Foreign credits
Income & Market Gain
This combines the two figures above to show the investment’s total return for the period.
Income & Market Gain = Change in Value + Income
Worked example
| Opening Value | $25,289.50 |
| Closing Value | $69,876.00 |
| Purchases during the period | $46,676.50 |
| Sales during the period | $0.00 |
| Change in Value | $69,876.00 − $46,676.50 + $0.00 − $25,289.50 = ($2,090.00) |
| Dividend/distribution income (ledger) | $1,373.77 |
| Franking credits | $41.04 |
| Foreign credits | $41.01 |
| Income | $1,373.77 + $41.04 + $41.01 = $1,455.82 |
| Income & Market Gain | ($2,090.00) + $1,455.82 = ($634.18) |
Why this can differ from the Investment Income Comparison Report
The Investment Income Comparison Report is sourced from ledger transactions (dividend and distribution income actually posted to the ledger). Unlike the Simple Dietz Report, it does not include franking credits or foreign tax credits, and it does not include interest income from bank or term deposit accounts – only dividend and distribution income.
Using the example above, the ledger recorded four dividend/distribution transactions totalling $1,373.77. This is the figure the Investment Income Comparison Report will display, whereas the Simple Dietz Report shows $1,455.82, as it also adds the $41.04 franking credit and $41.01 foreign credit.
If an investment is not appearing on the Investment Income Comparison Report at all, check whether its income was posted as interest (which the report excludes) rather than as a dividend/distribution, and confirm the income account is correctly linked to the investment account in the chart of accounts.
